Property Insights of montelukast

The XLogP value of 7.8897 indicates that montelukast is lipophilic (fat-soluble), which may influence its absorption, distribution, and formulation strategy. With a topological polar surface area (TPSA) of 33.12 Ų, montelukast exhibits relatively low polarity, potentially indicating favorable cell membrane permeability. Following Lipinski's Rule of Five, montelukast has 2 hydrogen bond donor(s) and 3 hydrogen bond acceptor(s), which may warrant consideration for formulation optimization.
